Summary

Business impact: Participants on this field course will learn to apply outcrops along the Devon and Dorset coast as geological analogues for some major CCS projects including Hynet (Hamilton), Endurance, Acorn/Goldeneye, and East Mey.

Using outcrop studies, participants will consider the effects of reservoir geometry, porosity, permeability, and geomechanical properties on CO2 flow patterns, storage, injectivity, reservoir strength, and behaviour at high fluid pressure. Analogues to top-seals for CCS sites will be considered, plus fault reactivation at elevated CO2 pressure, well design, and completions strategies.

Duration and Training Method

This is a field course supported by short classroom sessions.

Course Overview

Participants will learn to:

  1. Detail the effect of reservoir properties on CO2 storage capacity and CO2 injectivity. 
  2. Examine the influence of reservoir heterogeneity on CO2 movement patterns. 
  3. Explain how faults with different orientations and geometries may undergo reactivation at elevated CO2 pressures. 
  4. Develop strategies for considering possible CO2-water-rock reactions depending on host rock mineralogy and fluid chemistry. 
  5. Evaluate CO2 well completions strategies. 
  6. Appraise top-seals in terms of their lateral and stratigraphic variability of geomechanical and petrophysical properties. 
  7. Develop approaches for considering the possible extent of reservoir dilation and reservoir fracturing due to elevated CO2 pressure. 

The field course will visit reservoir and top-seal analogues to consider the following key topics:

  1. How reservoir geometry will affect CO2 flow patterns.
  2. The effect of reservoir permeability on CO2 injectivity.
  3. How reservoir porosity affects CO2 storage.
  4. The effect of geomechanical properties on reservoir strength and behaviour following CO2 injection (i.e., reservoir dilation, fracturing) at high fluid pressure.
  5. Reactions that may occur in sandstone and carbonate reservoirs, focussing on the rate and likelihood of dissolution versus precipitation of minerals.
  6. Top-seals for CCS sites - geometry, heterogeneity, permeability, capillary entry pressure, and advective CO2-loss, CO2 diffusive loss, and fracturing at elevated CO2 pressure.
  7. The effect of stress orientations in the subsurface relative to fault orientations and the possibility of fault reactivation at elevated CO2 pressure.
  8. The influence of rock properties on CO2 injection well design and completions strategies - weak (friable) vs. relatively strong (brittle) lithologies.

A full itinerary will be provided in due course.

This course is aimed at geoscientists and engineers, but other sub-surface staff will also find the course useful. Team leaders and managers of teams involved in CCS projects would also benefit from participation. This field course is suitable for multi-disciplinary team attendance.

Howard Johnson

Background
Howard Johnson has around 30 years of petroleum-related experience, divided equally between Shell and Imperial College London. He is currently the Shell Professor of Petroleum Geology at Imperial College, a position that he has held since 1993. He is Director of the MSc Petroleum Geoscience course (45-50 students annually), and Head of the Petroleum Geoscience and Engineering Research Section, which is a research-active, multidisciplinary group comprising 14 academic staff and around 50 PhD students and research staff. His personal research interests are in clastic sedimentology and reservoir characterization.

He has wide experience in delivering technical courses for petroleum industry professionals, including Development Geology, Reservoir Characterisation and Sedimentology. He has published around 50 technical publications.

Richard Worden

Background
Professor Richard Worden is leader of the Diagenesis Research Group and programme director of the MSc on Petroleum Reservoir Geoscience at Liverpool University. He has more than 30 years of industry and research experience.

Prof. Worden undertook a BSc in Geology and Geochemistry at the University of Manchester, completing it with a 1st class honours degree in 1984. Following a PhD at Manchester University in 1988, he worked for BP Research and BP Exploration in Sunbury, UK, for 6 years. This was followed by a lectureship at Queen’s University in Belfast until 2000 and then a professorship at Liverpool University.

Richard has worked on a number of areas of research, almost all related to oil and gas geoscience, with focus on high quality reservoir-scale data (including quantitative mineral and textural data, and the integration of petrophysical, petrographic, geomechanical, geochemical,  and sedimentological data) to help with oil and gas exploration, appraisal and asset management. He has worked extensively on sandstone reservoir quality throughout his career, with focus on the causes of anomalous porosity-preservation in deeply buried sandstone reservoirs. His research is now extending into reservoir property-related issues involved in the energy transition (CCS, hydrogen generation and storage).  He has published seminal papers on the role of microquartz coatings and on the effects of early oil emplacement on quartz cementation, with a key paper on chlorite-inhibition of quartz currently in press with the Bulletin of the American Association of Petroleum Geologists.
